Optische gesteentedeterminatie II. De Polarisatie-Microscoop

It is possible to make from every microscope a polarisation microscope, without high expense. Some supplies must be made,
among which the attachment of polaroid. For this can be used polaroid HN 22 - 0.03511. All details of the rebuilding are given
for the Japanese marks Polarex and Olympus (G.C. Model). With the latter type in its rebuilt condition it is possible to produce
the most common optical-mineralogical properties (as: interference figures, extinction, elongation, refraction). The price
can so been reduced ta nearly half the amount of a simple original polarisation microscope.
